To alt "Ir/mm it may comer.

Be it known that I, A LEXANDE S. SPIEGEL, citizen of the United States, residing at (hie-ago, Illinois, have invented certain new and useful Improvements in l mparatns for Forming Roofing-Shingles,of which the following is a specification.

This invention relates to machines for cutting shingles from prepared roofing and consists essentially in the knife for performing the cutting operation.

With these and other objects in view, the invention includes the novel features of construction and arrangenaint of parts hereinat'tcr described and more particularly pointed out. in the claims, it being understood that i do not intend to limit myself to the details of the different parts of my invention.

I have illustrated my invention in the ac companying drawings, in which-- Figure l is a side elevation of my invention. lig. 2 is a. top plan view of my improved device. Fig. 3 is a partial view showing the narrow knives in operation.

In the drawings, 1 indicates the roofing material, 2 cutters for cutting a straight slit forming two strips 16 and 17, 8 and 9 feed rollers, of any ordinary or improved construction. The rooting is Fed to a block to of particular construction to form an edge, which, while supportlng the roohng material, conforms to the shape of the cut ters so as to enable a shear cut to he made.

The shingles are made by rotary (utters which, as shown in Fig. cut out two central shingles from the center of the strip, when the strip is of double width and following cutters sever marginal shingles, the cutters having such relation to each other as to cut the shingles from the strips in staggeredrelation. The 'cutters are three in number, mounted upon a rotary shaft 1!) suitably driven, the center cutter, indicated at 21, having the configuration shown where it cuts into a double strip so as to cut out j tel-dim; means therelor and means for cut from the strip two complete shingles, the

allow a shingle port on, the shape of the knife 21, to be cut out and to fall through the opening. lhe knife 21 in its rotation passes through this opening. The dotted lines are to show where tl'm successive cuts of the respectiveknives will be made. The feed of rooting material to the block 18 is so timed in relation to the rotary shal't ll) that one shingle width will be fed to every revolution of the shaft. \Vhen it is remembered that the rooting is severed at 2-1 before it reaches the kni to 2], it can be seen how each cut of this knife severs two shingles while the luliies 2 sever one each.

The order of operation of. the central cutters and the marginal cutters is inuua terial, as one may begin rnd the others follow or vice versa without in any way at"- iecting the cllieient operation of the devices.

I do not limit; myself to the forming olf rooting shingles by this apparatus, as it may beadapted to the cutting ol other material.

l claim as my invention 1. The herein described machine comprising supporting and feeding means for the material to be operated upon and means for sina-essively cuttim sections therefrom and simultancously in the cutting action form ing the complete end of one section and halt of the ends ol two adjacent sections, the ends of the omuosing sections being cut in stw gered relatiommith means for severing 2 the sections from the body material latch ally, substaz'tially as descrila d.

it. in a. machine l'or forming shingles from a strip or sheet oi rooting material, supporting and i'oediug means tor the material, and cutters successively cutting from said strip or sheet shingle sections lirst from line of severance between having been made 1 by cutters of severance for the marginal shingles Fig. 3 shows the knives 20 pin-forming a cut on the outer portim'ls of the strips H3 and 17. Fig. 1 shows the knife 31 in cutting position over the block 18, wherein is an opening 23 to correspond to the shape of the knife 21 which operates therewith to Side cutters 20 make the line one side and then from the other of said strip. the ends of the opposing sections being cut in staggered relation to each other to form ornamental ends, substantially as do scrila-d.

2). in a machine for l'orming shingles. a strip or sheet of material. supporting and ting out therefrom at one opcratimi a complete shingle and forming the ornamental end of a part of two other shingles, the ends-1 ol' the opposing sections being cut in staggered relatioin .mbsLanlially as described.

4. in a machine for l'ormiug shingles from a strip of roofing man-rial, supporting and feeding means therefor, a cutter for Lil) 0i mam, h 11n- Pa ans I91" g the last n 1 mad. sections Jam the substantial from m a mezm iilerefar and z itary cutter adapt sd 30 :tuic from the strip my: aperamnn time sfie ends 01 (me slum-- and? feeding means, a rainy cutter for sew mung from the stmp a complete shingle and forming a part of the en'ds of two ad acent shingles with additional means for sevex-ing thereby completing the said adjacent sshmgles followmg the when of me rotary cutter, substantially as deswibed.

testimony whereof, I affix my signature 1n presenceni two itnesses.
